SAKO adjustable stabilized voltage constant current DC switching power supply / Adjustable DC power supply adopts the switching power supply technology of without Industrial Frequency transformer, so DC voltage regulator has the input function of AC/DC compatibility and wide input voltage range. DC voltage regulator adopts the advanced switching power supply control technology, components and aborative design, the DC voltage regulator has small volume, light weight, high efficiency, which ensures the stability and reliability of long-term full-load operation. DC voltage regulator has the perfect protection function. Build-in temperature control radiator fan, which not only effectively radiates but also effectively prolongs the lifetime of fan; Over-temperature automatic switch-off protection, output over-voltage, over-current and short-circuit protection. Soft starting when switch-on delays. DC voltage regulator can avoid output voltage overshoot when switch-on. The DC voltage regulator and DC voltage stabilizer is widely applied to electric power DC screen system, engineering control, communication, scientific research, charge of storage battery etc. equipment.

Technical DATA
Features
1. AC/DC compatible input, input voltage range width
2. Maximum Output:48V and 40A, maximum output power: 2000W
3. Adopting to the advanced switching power supply technology and components, elaborate design, small volume, light weight, high efficiency, which can ensure the stability and reliability of long-term full load operating.
4. Constant voltage value and constant current value can be continuously adjustable within the range of respective maximal value (0~100%). The output constant current value is adjustable, which brings convenience for a lot of applications, such as plenty of debugging applications, and lowering the constant current value can conveniently and efficiently protect the safety of load equipment.
5. Set up the perfect protection function. Build-in temperature control radiator fan, which not only effectively radiates but also efficiently, prolongs the lifetime of fan; over-temperature automatic switch-off protection, output overvoltage, and overcurrent and short-circuit protection. Implement the soft starting when switch-on delays in order to avoid outputting over-swing voltage when switch-on
6. The display output voltage and output current, and they are respectively independent display.
7. Simple operation, convenient use
8. Main Purposes: The power supply is widely used in electric power DC screen system, engineering control, communication, scientific research, charge of storage battery, etc. equipment
